GEORGE SfHAWIE, OF BRIDGEPORT. CONNECTICUT.

BUCKLE.

Application filed August 25, 1924.

To all fwzom.v t may concer/l1:

Be it known that I, GEORGE SqHAwin, a citizen of theA United States, residing at Bridgeport. county of Fairfield. State of Connecticut, have invented a new and useful Buckle, of which the following is a specification.

rllhis invention relates to a buckle, and has for an object to provide an improved buckle which will bevery simple in construction and may be manufactured at low cost, and which will have improved means for securing the free'end of a` web thereto Y 'to do away with the ordinary stitching operation and lto reduce the length of web required.

llVith the foregoing and other objects in view, I have devised the construction illustrated in the accompanying drawing forming apart of this specification, similar reference characters being employed throughout the. various figures to indicate corresponding elements. Iii-this drawing,

Fig.` 1 is a longitudinal section through the web and improved buckle showing the buckle in closed position.

Fig. 2 is a rear elevation thereof.

Fig. 3 is a detailsection substantially on line 3-3 of 2. y

Fig. 4 is a transverse section substantially on line 4.-/1 of Fig. 2, and showing the method of clamping the web to the buckle.

Fig. 5 is a. rear elevation of a.- buckle in open position showing a slightly Vdifferent construction.

Fig. 6 is an elevation looking from the right of Fig. 5 and Fig. 7 is a transverse section substantially on line 7-7 of Fig. 5.

My improved buckle comprises a sheet metal frame 10 provided with a pivotal support for the clamping lever 11. This support is preferably a continuous pivot bar 12 formed in one piece or integral with the bodyof the frame, and the connecting elements 13 are rounded to form strengthening ribs 14. These ribs materially strengthen the connecting elements without increasing their width and retain the pivot bar in proper position with respect to the body of the frame.

Improved means is provided for clamping the free end of the web 15 -to the frame which does away with the ordinary stitching operations or the metal clips which are sometimes used in place of the stitching. For this pur- Serial No. 733,926.

'securing means and also gives greater strength to the frame as there is a central connection 17. The free edge 18 of the frame is bent rearwardly from the body of theframe adjacent one edge of the openings lo. in the form shown in Figs. 1 to -l adjacent the inner edge of these openings. Before the web is secured in position the free edge of the frame is left substantially as shown in Fig. 4 to allow plenty of room for insertion of the free end 19 of the web 15. After the free end of the web is inserted, as shown in Fig. 4i, the clamping portion is placed between the movable jaws 2O of a suitable press and its free edge 18 clamped against the back surface of the web, as shown in Fig. 1. Theopposite or outer edges of the openings 16 are provided with teeth 21. preferably substantiallyv V- shaped as shown. with the free ends of these teeth bent slightly inward from the plane of the frame `and extending in a direction away from the open end of the clamp. It will be apparent that when the bent over portion of the frame is clamped against the `web the free endsof these teeth will be.

forcediinto the web somewhat. and as they extend in the opposite direction from the direction of strain on the web tending to pull it away from the clamp it will be apparent that the teeth will securely hold the web in the clamp. The web is then bent backwardly and downwardly over the free edge 1S of the clamp and is threaded around through the frame through the opening 22 between the body of the frame and the lever 11. and is clamped by the lever in the usual manner, as shown in Fig. 1.. It will thus be apparent that this buckle .is of the rustless type as the back is entirely covered b v the web, and also requires a. minimum amount of web for the purpose of securing it to the buckle.

In Figs. 5. 6 and 7 l have shown a slightly different arrangement of the clamping means for the free end of the web. In this construction the frame 23 is provided with elongated openings 24 similar to the openings 16 but located a somewhat greater distance from the free edge Q5 of the fra-me.

The frame is bent rearwardly upon itself away from the open side of the clainp so lother form.

` through the opening 'that they engage and hold t-he web in the saine inannei' as do the teeth in the fo 'in shown in Figs. l to 4. The first forni is preferred, however, as it does not weaken the body of the fraine as inuch as does this form. vIn the second form the web is folded over the free edge 25 the saine as in the first forni, and isl then threaded through the opening 22 in the fi-'aine theV saine as in the Having thus set forth the nature of my invention, what I claiin is:

l. In abuckle, a sheet metal fi'aine having a pivotbarV adjacent one edge7 a securing `leverpivoted'to said bar, said frame being provided with an opening adjacent the other edge and bent backwardly upon itself and adjacent one edge of said opening to forni a clainp for the free end of the web, the other edge of said opening vbeing provided with teeth spaced: from the first edge of the opening to engage said web. A

2. In a buckle, a sheet metal fraine, a securing lever pivoted to said frame, the lower portion of said frame being provided with an elongated opening and bent rearwardly upon itself through the opening to form a clainp for the free end of the web,` one side vof said opening' being provided with teeth spaced from the bend and extending in a direction away from the open side of the clamp to engage said web. l

y 3. In a buckle, a lsheet inetal frame,VV a se-v curing lever pivoted to said fraine, the lower portion of said f raine being provided with an elongated `opening'a'ifid bent rearwardly upon itself through the opening adjacent the inner edge of the opening to forin a clanipV i f from the open side of the clanip to engage the web.

4. In a buckle, a sheet inetal frame having a pivot bar adjacent one edge thereof, a'see Y. curing lever' pivoted to `said bai"7 said frame being Yprovided adjacent its opposite edge withone or more elongated openings and bent backwardly upon itself through said opening oiropenings adjacent the inner edge of said opening or openings to provide a clainp for the free end of a web, the other edge of the opening or openings being provided with teeth spaced from the'bend extending inwardly from said edge in la cli-jV rection away troni the open side ofY the j' clainp to engagethe web. Y ,Y

In a buckle, a onefpiece Isheetnietal fi'anie having a pivotbar at one edge thereof, the connectionsbetween the bar and the bodyof the'fraine being curved transversely to forni strengthening ribsfsaidV frame being provided adjacent its oppositeedge with one or incre-elongated` openings and bent Vrearwardly upon itself through the opening or openings adj acent one edge of theY opening` to forin a clamp for thefree end of a web', the opposite edgeof theopeningjor openings being provided with teeth spaced Afrein the bend and extending inwardly in a direction' away from the open side of the clainp to en!" gagesaid web, and -a clamping lever pivoted to said bar.
